Rolling-mill.



evapora 1To Aallavhofm' it may concern: B e it known that we, EMIL EBINGHAUs and ALBERT SGHUMACHER, citizensfof tlie v German Empire, re'sidinr at Gevelsberg, in

` carried forward one Way by a segiie the Province of West balia and Kingdom of Prussia, Germany, ave invented'- certain new and useful Improvements in Rolling*- Mills, of which thefo wing is a specificaregular. order and which forms th`\ counter mold for the revolving roller.' 'This slid toothed gearing. engaging during a 'made in one .piece with the same and it 1 r in period of itsrotationwiththe correspo di teeth 'of 'a rack connected to the table or pulled back, wlienit hasv become disengaged from the roller by means of a'counterweight suitably 'arranged so as to vexert a pulling force in the proper direction upon the slide,

asWill be more fully described hereafter.

`On the `accompanying drawing the new 4rolling mill is shown inv a vertical sectional view in Figure 1in osition Where the segmental gearing and tllie rack of the slideare in gear with each other, iii Fig. 2 that position of the slide plate is shown 'and of the roller, where the yrack and toothed segment are disen aged with each other and Where the slide as been pulled back into its original' osition.

T e machine is supported on a table 1, carrying in suitable guide ways `the slide 2: at one end of the slide is fixed a rope or chain 3 passing over a pulley 4 of a bracket 5 and to the endof which isI suspended a counter'- weight 6 having the tendency to pull the slide always towards one side, the left iii the examples l eral projection 7 ofthe table 1.' Right and left toboth sides of tlie slide the table' carries .the forked ystand ardsy or upriglits 8 which serve as guides for the brasses 9, indicated m dotted lines, in which the shaft 10a of the l roller 10 is journaled; at one end the shaft carries a driving pulley 10b by which the " rollerjl() is set in continuous rotation. It is *self evident that instead of this direct dri.v-

The roller 10 is provided ith an exchangeable molding gilece or calibdilll fitted thereto firmly but:l ta 'ng only part.l of the circumference, say about one ifth or onesixth of the same, and in accordance herewith the roller is provided with a toothed segmental part 12; this may be connected to the roller or fixed separatel on the rollershaft. The

slide 12 is iii-a simi ar and corresponding manner provided with anexchangeable molding piece 13 and-with arack 14 corresponding with" the toothed segment 12. `The roller is pressed down by its own weight.

From 'the description given and from the .-drawing the Working of the machine. will now be easily understood to be as follows: A pliece of iron or steel, preferably made red ot is laced on the molding piece 13 and when t e toothed segment 12 comes round and engages with the rack 14'the slide 2 is driven towards the right together with the working piece upon it and this is pressed between the two molds 11 and 13 and thus receive's its shape; as soon as the last tooth of the segment leaves the rack 14, the slide is pulled back by the rope and counterweight 3, 6, 'the worked piece or pieces can now be taken off and a new work piece be placed on.'

the mold 13, when the same pla'y is repeated. The brasses 9 are free to rise in or between the standards 8, which have their slot or in# tervening guide-wav open at the top. In consequence the roller 10 will readily yield upward incase of sudden jar, preventing any injury. Also the insertion of thicker material to beA operated on will be facilitated. Having nowdescribed our invention and its inode of Working, we declare that what we desire to, be secured by Letters Patentjis: 1. In rolling mill mechanism a longitudinally movable part and a die carried thereby, in combination with an axially movable part, a coperating die carried by. the latter, and a frame adapted to support said parts and permit and guide such movements, the axially movable part being free to move vertically upward for admitting greater thickness of material or preventing injury by sudden jars substantially as set forth. l

2. In rolling mill mechanism a pair of co- .operating die-carrying members, one moving 'member and its die being-'Hee to 'i'se in case vYlitnessles:
